  1. Much Ado About Zone 2

    Much Ado About Zone 2

    Influencers can’t get enough of Zone 2 low-intensity training. So why did Martin Gibala publish a research paper challenging Zone 2 for the general public? In this episode, Stuart Phillips leads Marty through a critical examination of Zone 2.  Marty suggests that very little scientific research exists to support Zone 2 training intensity for most people—either as an effective stimulus for cardiorespiratory fitness or mitochondrial capacity. In fact, if you do between three and six hours of cardio a week, Marty believes that Zone 2 isn’t hard enough for you to efficiently accrue training benefits. In other words, if you’re an amateur athlete subscribing to the much-vaunted rule that 80% of your cardio should be in Zone 2, you’re not as fit as you otherwise could be.  So what is Zone 2 training? And is Zone 2 causing many people to exercise inefficiently, leaving them less healthy than they otherwise might be? What should people be doing INSTEAD of Zone 2? It’s all here, in the latest episode of Exercise Science!  Have a listener question or an idea for an episode?

  2. Strength Training for Everybody!

    Strength Training for Everybody!

    Our co-host Stuart Phillips was the senior author on the ACSM’s gold-standard strength training position statement, a.k.a. “the most comprehensive evidence-based guidance to date on how resistance training supports muscle strength, muscle size (hypertrophy), power, and physical performance across adulthood.”  In the premiere episode of Exercise Science, co-host Martin Gibala takes Stu through the American College of Sports Medicine update, the first position statement in 17 years.  Parsing the science, together, Stu and Marty break down why strength is the ultimate compound interest investment for your health span. How important is strength training? Why should you consider strength training 2x per week to be just as important as the other main exercise-related health guideline, 150 minutes of moderate-intensity exercise per week?  Plus: How much strength training is enough? What’s the minimum that you should do? What changed during the 17 years between position stands? And how did a 1940s bodybuilding doctor rehabbing soldiers pave the way for modern strength training?Forget the oiled-up pumping-iron musclehead stereotype. In 2026, strength training is officially for EVERYONE. And if you’re going to listen to just one podcast about the new guidelines — make it this episode of Exercise Science! LINKS Exercise Science is everywhere @realexercisescience: Substack. YouTube. TikTok. Instagram. Apple Podcasts. Spotify.

ACSM Position Stand 2026: The scientific article in Medicine & Science in Sports & Exercise  Here’s the press release about the stand from the ACSM, and a great succinct infographic summarizing the main takeaways Here are the two previous ACSM position stands on strength: 2009 and 2002  Thomas L. DeLorme and the Medical Acceptance Of Progressive Resistance Exercise - Iron Game History Thomas L. DeLorme and the Science of Progressive Resistance Exercise - Journal of Strength and Conditioning Research (Abstract) Among the four students on the position stand, Stu said Brad Currier brought the evidence together, did the lion’s share of the writing and herded the cats All about Ken Cooper, a seminal expert on aerobic fitness who came to understand the importance of strength training  Honoring the legacy of Steve N. Blair, a giant in the field of exercise epidemiology Marty and Stu’s MOOC: Hacking Exercise for Health Exercise Science is produced by Ghost Bureau in Toronto.  DISCUSSION POINTS 00:00 Marty teases Stu 01:20 Episode outline 02:34 What’s a position stand? 03:36 What is the ACSM? 03:52 Building the team 05:00 What’s new in 2026 06:20 Levels of scientific papers 07:10 2026 v. 2009 08:12 Recommendations 09:30 Effort v. failure 10:38 Volume of training 12:30 Home-based options 14:06 Advice for newbies 15:13 Strength explained 18:57 Power explained 19:37 Why now? 22:17 Weight training for women 23:03 Capt.
